These and other recoverable uranium ores, as sources of nuclear fuels, contain many times more energy than all the known recoverable deposits of fossil fuels.One pound of uranium yields as much energy as 1.4 million kilograms (3 million pounds) of coal.The chronicle of this great change can be broken into five periods; ran from AD 1600-1700.In this period a number of comprehensive cosmogonies were proposed.
Natural uranium, therefore, can be used in converter and breeder reactors, in which fission is sustained by the rare uranium-235 and plutonium is manufactured at the same time by the transmutation of uranium-238.
In short, Genesis was an allegory and not literal history.
The story of this great change in the conception of the history of Earth is not a simple one.
Fissile uranium-233 can be synthesized for use as a nuclear fuel from the nonfissile thorium isotope thorium-232, which is abundant in nature.
Uranium is also important as the primary material from which the synthetic transuranium elements have been prepared by transmutation reactions.
If you asked the same question of an educated European in AD 1900 you would have received a quite different answer.
